I have provided a beard depressor vented certain new and useful Improvefor each needle, and said beard depressor is ments in Circular-Knittin Machines, wheremounted in the channel formed for the of the following is a specification, reference needle, and is so constructed that it rOcks being had to the accompanying drawings. laterally into engagement with the heard of The invention relates more particularly the needle atthe proper time. A stationary to the mechanism for depressing the spring cam is carriedby the supporting plate at the beard of a knitting needle, whereby the head of the cylinder, for rockingthe beard loops of yarn are shed therefrom. depressor into engagement with `the needle, An object of the invention is to provide a While a suitable spring or other yieldn beard depressor for each needle, which is so means mounted on the cylinder, automatlconstructed as to move with the cylinder cally withdraws the bea de ressor from and also to move independently thereof in a, engagement Ywith the needle w en released direction radially of the cylinder for closing by the stationary cams.
